SCCP pick-up problem

Hello, all,

I have the following problem with my * PBX:

I have more SIP phones and one SCCP phone. They are all in the same callgroup and pickupgroup. The pickupexten is 999 and, long story short, everything goes well between the SIP phones.

The problem comes when the SCCP phone gets a ring and one of the SIP phones tries to pick it up. I get the following error:

ail*CLI> core set verbose 5
Verbosity is at least 5
– Executing [284@from-sip:1] Ringing(“SIP/289-08259308”, “”) in new stack

– Called 284

== Spawn extension (from-sip, 284, 2) exited non-zero on ‘SIP/289-08257d80’

I’m lost here… what could be the cause for this behavior? Help would be greatly appreciated!

ps: I have no problem picking up calls that originate from the SCCP phone, only vice versa.[/i]
